WING.

Specification of Letters Patent.

Patented Aug. 3, 1920.

Application filed March 15, 1920. Serial No. 366,021.

To 071 whomr it may concern:

Be it known that I, HARRY M. WoLrE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York,

have Ainvented a new and Improved Wing, of which the following is a full, clear, and exact description.

The invention relates to aeroplanes and other aerial machines, and its object is to provide a new and improved wing more especially designed for use on a fighting air craft. and not liable to collapse when subjected to heavy strains or when riddled with bullets.

Another object is to render the wing exceedingly strong and durable and capable to readily withstand heavy wind pressure.

lVith these and other objectsin view, the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate coi'- respondingr parts in all the views.

Figure 1 is a plan view of the improved wing with part of the covering broken out;

Fig. 2 is an enlarged sectional side elevation. of the same on the line 2 2 of Fig. 1;

Fig. 3 is an enlarged cross section of the same on the line 3 3 of Fig. l; and

Fig. 4t is a perspective view of one of the connecting members for connecting the covcring with the ribs and connecting adjacent ribs with each other at their points of contact.

The improved wing consists essentially of a frame and a covering, of which the frame is formed of metal ribs 10 extending fore and aft and sinuous in form when viewed in plan, as plainly shown in Fig. 1. The ribs 10 are arranged side by side and in contact with each other at the ends, middle and intermediate points, that is, two adjacent ribs form a pair of ribs and are in contact with each other at their ends and at their middle, while the adjacent ribs of two adjacent pairs of ribs are in contact with each other intermediate the middle and the ends, as will be readily understood by reference to Fig. l. The top and bottom edges of the ribs 10 are given the usual shape of the wings of aeroplanes as now generally constructed and as shown in Fig. 2 so that further description of this feature of the wing is not deemed necessary. It is understood that the ribs 10 associated in the manner described form a frame and this frame is inclosed in a covering .11, preferably made of sheet metal, and having a top and a bottom overlying the corresponding top and bottom edges of the ribs 10 and being secured thereto by spot welding and also by the use of fastening members 12 in the form of clips extending through the covering 11 at the top and bottom and straddling the adjacent ribs at their points of contact. The clips are preferably soldered or otherwise fastened to the top and b'ottom of the covering l1.

From the foregoing it will be seen that by the arrangement described an exceedingly strong and durable framework is provided and one that is not liable to break asunder in case of the wing being riddled by bullets.

It is understood that I do not limit myself to the particular sinuous form of the ribs 10, as shown and described, as other curved or corrugated shapes may be given to the ribs without deviating from my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A wing for aerial machines, comprising a frame formed of members extending fore and aft and each of curved shape when viewed in plan, the members having contacting portions and secured together, and a covering for inclosing the said frame.

2. A wing for aerial machines, comprising a frame formed of members extending fore and aft and each of sinuous shape when viewed in plan, the members being arranged in pairs and the contacting portions of the members of each pair being fastened together, and a covering inclosing the said rame.

3. A wing for aerial machines, comprising a frame formed of members extending fore and aft and each of siniious shape when viewed in plan, the members being arranged in pairs, the contacting portions and the ends of the members of each pair beiner fastened together, the adjacent members o adjacent pairs being fastened together at the points of contact, and a covering inclosing the said frame.

4. A wing for aerial machines having a frame formed of ribs of sinuous shape when viewed in plan, the ribs being fastened together alternately at the middle and at points intermediate the middle and the fore and aft ends.

5. A Wing for aerial machines having a frame formed of ribs of sinuous shape When viewed in plan, the ribs being fastened together alternately at the middle and at points intermediate the mlddle and the fore and aft ends, a covering inclosing the said frame, and fastening means connecting the covering with the ribs and the ribs with each other at the middle and at points intermediate the middle and the ends.

6. A wing for aerial machines, comprising a frame formed of ribs extending fore and aft and of sinuous shape when viewed in plan, adjacent ribs having points of Contact,

a covering inclosing the frame, and fastening members in the form of clips seated on the covering and straddling'the ribs at their points of contact.

7. A wing for aerial machines, comprisin a frame formed of ribs extending fore an aft and of sinuous shape when viewed in plan, adjacent ribs having points of contact, the ribs being arranged in pairs, the ends and middle portions of the ribs of a pair being in Contact, and adjacent pairs of ribs being in Contact intermediate the middle and ends, a covering inclosing the frame, and fastening members in the form of clips seated on the covering and straddling the ribs at their points of Contact.
